SYNOPSIS

DESCRIPTION

Archive::Tar::Files provides a neat little object layer for in-memory
extracted files. It's mostly used internally in Archive::Tar to tidy
up the code, but there's no reason users shouldn't use this API as
well.

Accessors

A lot of the methods in this package are accessors to the various
fields in the tar header:

Methods

Archive::Tar::File->new( file => $path )

Returns a new Archive::Tar::File object from an existing file.

Returns undef on failure.

Archive::Tar::File->new( data => $path, $data, $opt )

Returns a new Archive::Tar::File object from data.

$path
defines the file name (which need not exist), $data
the
file contents, and $opt
is a reference to a hash of attributes
which may be used to override the default attributes (fields in the
tar header), which are described above in the Accessors section.

Returns undef on failure.

Archive::Tar::File->new( chunk => $chunk )

Returns a new Archive::Tar::File object from a raw 512-byte tar
archive chunk.

Returns undef on failure.

$bool = $file->extract( [ $alternative_name ] )

Extract this object, optionally to an alternative name.

See Archive::Tar->extract_file
for details.

Returns true on success and false on failure.

$path = $file->full_path

Returns the full path from the tar header; this is basically a
concatenation of the prefix
and name
fields.

$bool = $file->validate

Done by Archive::Tar internally when reading the tar file:
validate the header against the checksum to ensure integer tar file.

Returns true on success, false on failure

$bool = $file->has_content

Returns a boolean to indicate whether the current object has content.
Some special files like directories and so on never will have any
content. This method is mainly to make sure you don't get warnings
for using uninitialized values when looking at an object's content.

$content = $file->get_content

Returns the current content for the in-memory file

$cref = $file->get_content_by_ref

Returns the current content for the in-memory file as a scalar
reference. Normal users won't need this, but it will save memory if
you are dealing with very large data files in your tar archive, since
it will pass the contents by reference, rather than make a copy of it
first.

$bool = $file->replace_content( $content )

Replace the current content of the file with the new content. This
only affects the in-memory archive, not the on-disk version until
you write it.

Returns true on success, false on failure.

$bool = $file->rename( $new_name )

Rename the current file to $new_name.

Note that you must specify a Unix path for $new_name, since per tar
standard, all files in the archive must be Unix paths.

Returns true on success and false on failure.

$bool = $file->chmod $mode)

Change mode of $file to $mode. The mode can be a string or a number
which is interpreted as octal whether or not a leading 0 is given.

Returns true on success and false on failure.

$bool = $file->chown( $user [, $group])

Change owner of $file to $user. If a $group is given that is changed
as well. You can also pass a single parameter with a colon separating the
use and group as in 'root:wheel'.

Returns true on success and false on failure.

Convenience methods

To quickly check the type of a Archive::Tar::File
object, you can
use the following methods:
